Abstract

This study the woody species diversity in Shariati Park of Khorramabad township was evaluated. A number of 30 sample plots were sampled of park using systematic random sampling technique and in each sample plot characteristics of plant species, number of species, diameter at breast height of all trees, height of all trees and shrubs as well as large and small diameters of crown were measured. Simpson's evenness index as well as Simpson, Shannon-Weiner Hill, and Brillouin diversity indices were used to assess woody diversity in this park. The results show that Shariati Park had the average Shannon (0.886), Simpson (0.469), Hill (1.729) and Brillouin (0.591) also this park has the average Simpson evenness index (0.746) and the average species richness (2.36). In order to explain the structural parameters of height, diameter distribution curves, mean of diameter, height of  Shariati Park  were 21.74 cm and 10.14 m, and mean basal area equal to  403.352 cm2 obtained. Based on these results, the diversity and species richness are fewness in urban Shariati Park.
